Ordinary WiFi can now identify people with near perfect accuracy
Scientists in Germany have demonstrated a startling new form of surveillance: identifying people using nothing more than ordinary WiFi signals. By analyzing how radio waves bounce around a room, researchers can effectively “see” and recognize individuals — even if they are not carrying a device and even if their phone is turned off.
Researchers in Germany have developed a novel method for identifying individuals using standard WiFi signals. This technology analyzes the way radio waves interact with a person's body as they move through a space. The system can then recognize specific individuals with a high degree of accuracy based on these unique movement patterns.
This breakthrough raises significant privacy concerns as it allows for the tracking and identification of people without their knowledge or consent, even without them carrying a device.
